A measure of the capability of a solute for hydrophobiclipophilic interaction based on the partition coefficientMath - text for distribution of the solute between octan-1-ol and water. The most general way of applying Math - text in correlation analysis, QSAR, etc. is as log Math - text, but the behaviour of substituted benzene derivatives may be quantified by a substituent constant scale, Math - text, which is defined in a way analogous to the Hammett σ scale. There are various scales, depending on the substrate series used as reference.
